Description:
------------
Converting of object to string does not work properly. The code below explains all.

Reproduce code:
---------------
<?php
class Foo {
    function __toString() {
        return "What ever";
    }
}

$obj = new Foo;
$str = (string) $obj; // call __toString()
echo $obj; // call __toString(), prints "What ever", it's good
print $str; // prints "Object id #1" it's not good
?>
